50 Cent 'sets up P Diddy petition'

50 Cent has apparently taken another swipe at P Diddy, this time launching a petition against him.

The feud continued this week as the rapper called Diddy a "bitch" after previously saying that he wasn't a "real artist".

Perez Hilton reports that 50 Cent has now created a petition claiming that the hip-hop mogul is exploiting the memory of Notorious B.I.G., who was shot dead in 1997.

The petition reads: "Enough is enough, Biggie's name should never have become Diddy's Black Card. Just check out his latest video 'The Ghost of Christopher Wallace'.

"Let Diddy know to let B.I.G. rest in peace. When was the last time Diddy really was 'biggin' up his brother', not biggin' up his bank?"

Over 1,300 have now signed the petition via Twitter.
